The insertion of phenyl isocyanate into titanium isopropoxide leads to the formation of a dimeric complex [Ti(OiPr)2(μ-O iPr){C6H5N(OiPr)CO}]2 (1) which has been structurally characterized. Reaction of titanium isopropoxide with two and more than 2 equiv. of phenyl isocyanate is complicated by competitive, reversible insertion between the titanium carbamate and titanium isopropoxide. The ligand formed by insertion of phenyl isocyanate into the titanium carbamate has been structurally characterized in its protonated form C6H5N{C(OiPr)O}C(O)N(H)C6H 5 (3aH). Insertion into the carbamate is kinetically favored whereas insertion into isopropoxide gives the thermodynamically favored product.

The insertion of an isopropoxide ligand of titanium isopropoxide into heterocumulenes gives a product that carries out metathesis at elevated temperatures by undergoing insertion of a second heterocumulene in a head to head fashion, followed by an extrusion reaction.

Reaction of isocyanates with alkyl N-phenylcarbamates

, p. 610 - 612 (2007/10/03)
Alkyl N-phenylcarbamates accelerate thermolysis of isocyanates by forming with the latter at the first stage of the thermolysis a donor-acceptor complex. The accelerative effect of the carbamates is enhanced by increasing electron-donor power of substituents in the carbamates and increasing electron-donor power of the isocyanates.
